As announced on sys-announce we will shortly be migrating all the existing Informatics cloud printers to the EdPrint system. The blurb from Information Services: What’s happening and when? Information Services is launching EdPrint over the next few months, a major update to the print, copy and scan service used in the University. The cloud print […]

If you don’t use any servers in either of the Forum self-managed server rooms, then please ignore this blog post – and have a nice day! However, if you do use any such machines, then it is important that you read the following, and fully understand the situation concerning power to those machines. We are […]

For security reasons we are reviewing our use of user authored CGI scripts that are currently running on our web services. Those CGIs that run as the author, such as those on homepages.inf.ed.ac.uk and sweb.inf.ed.ac.uk, are not under review at the moment, but other CGIs that run as the web server daemon are. The main […]

Earlier this year, we mentioned that we intended to replace the Uninterruptible Power Supply (UPS) system which supplies power to all of the server rooms located in the Informatics Forum – see our blog post Forum server room UPS from January 24, 2019. Since then, we’ve been doing lots of preparation, and we are now […]

With the introduction of the University’s centrally provided blogging service (blogs.ed.ac.uk), no new blogs will be created on the Informatics blog.inf.ed.ac.uk and wp.inf.ed.ac.uk services. The central service is based on a current version of WordPress, and has a selection of modern themes, and plugins, including an EdGEL one to match the University’s branding. Using the […]

We are about to upgrade all rack power bars in the Informatics Forum self-managed server room IF-B.Z14. We will be replacing the existing metered power bars (APC models AP7853 and AP8853) with switched versions (APC model AP8953). The new power bars will allow us fine-grained control of individual power outlets; they’ll also help us prevent […]

Last weekend (Saturday 19.1.19), the UPS system which supplies power to the various server rooms located in the Informatics Forum developed a fault which meant that one half of the pair of units which comprise the UPS went off-line. As a result, the other half of the pair became overloaded: we now have so many […]

We will soon be replacing all existing 100 Mb/s network switches in all of the Informatics Forum IT closets with new 1Gb/s switches. There are 17 IT closets in the Forum, each of which provides networking connectivity to its nearby offices. Typically, each closet contains three or four 100 Mb/s switches – so there is […]

The web server that hosts the groups.inf.ed.ac.uk web site (and various others) is one of the last to be upgraded to SL7. I had hoped to squeeze it in before the end of the year, but it will now happen on Friday January 12th 2018. The groups.inf web server actually hosts multiple sites, the main […]

Good news! We are extending the Forum self-managed server room facility by adding three brand new racks in a nearby room. Bad news! To arrange the necessary power feeds to the new room, we will need to completely switch off the power to the existing self-managed server room for a short period next week. The […]
